Playing Xayah causes my game to crash

So I have noticed something very odd with Xayah and that is when I play her I suddenly get extreme lag to the point it crashes my game. Every other champ in the game doesn't have this problem but for some odd reason Xayah does only when I am playing her, playing against her is fine no problems but playing her something causes this extreme lag and crashing. Can anyone explain this and has this happen to anyone else?

Also, I have my settings to the lowest possible settings and other champs like Zyra (since she can spawn a ton of plants) don't cause any lag for me.
